Operation cycle

One complete cycle of a door begins with the door in the closed position. The door is then moved to the open position and back to the closed position again. The number of cycles is a unit of measurement for the longevity of the mechanical spring component of the door. The springs generally offered on the market have a service life of 10 000 cycles representing more than 13 years of operation at 2 openings per day. The Dura+ springs in the Garaga garage door hardware offer twice the longevity.
